TOP-ROLL SADDLE.

7 '0 all whom it may conce'rn:

lie it known that I, Ezra Drxox, a citizen of the United States, residing, at Bristol,

in' the county of Bristol and State of Rhode Island,'have invented a new and useful Im provement in 'lop-Roll Saddles, of which the following is a specification.

This invention relates to certain new and useful improvements in top roll saddles, and the primal object thereof is to provide means whereby the. objection of imperfect drawing of certain yarns by reason of failure to relieve the center roll of the weight of the saddle and the tensioning means thereof is obviated.

il n mills great troubie is experienced by the reason of the helps carelessness in moving-the, back saddle so that when the machine was originally set fo rthe weight on the front roll and the back roll, the weight is-through carlessuess moved-onto the center roll, with the result that imperfec rawing made for certain \'arns.

"lhe. present invention brietly proposes the provision of a reversil'de back Saddle, which will obviate the objection noted as :-the back saddle must he: removed and i'eversed to 'hring the weight upon the center roll, when such \\-(l L l|t IS not desired.

portions of apertures 5 in. lugs ti that are borne by the bottom saddle The bottom saddle 7 has the usual depending stop lingers 8 the, latter heinga-ngageable -\.vith the bearin; of the top rolls I: and v reference to th drawings it will lie seen that the [hi fJ 'l'S 8 are positioned closer to one end of the. bottom saddle than to the opposite end thereof, thus in effect causing the bottom saddle to have. a lon and a short end, the purpose of which will hi now pparent.

\Vhen it is desired to place the weight old on the. rolls/r. and (1 al'terthe machine. hasheenrunning with the weight on all three of the rolls, it is merely necessary to Specification of Letters Patent.

remove the back saddle from-thetail of the front saddle and reverse same,='a-n'd then replace the back saddle on the'tailofthe front saddle. so as to cause the front saddle to engage with the roll a and the hack saddle with the roll 0 and throw the weight on said rolls. In Fig. 1 in full lines the saddle is shown engaged wit-h all threeof the rolls while in the dotted line position in Fig. 1 the back saddle has been reversed and replaced on the tail or shaft 2 of the front saddle. and in such reversed position can only engage the roll 0, due to the provision of the long and short endsof the back saddle as aforementioned.

It will thus be apparent that in one position the hack saddle can engage. two rolls,

and in its reversed position it can only e11 so one roll which thus efi'ects vthedesidermum of preventing the-operator from bring.- ing pressure to bear on the center roll to draw certain yarn which does not require application of weight on'ztjhe :center ro'l l, since the short end of the bac k saddle is incapable of engafringthecenter roll I) when the short end of the ba'clc saddle points toward the :head of the front saddle.

lneidentally the. present invention .provides .means whereby effective lubrication .of the back addle throughout its entire length, and thus necessarily incl-udingftheshortland long end, is had. such means consisting of I a wick 9 arranged in a longitudinal channel 10 extending the. length of the baok saddle 7 the eha nncl traversingthe-fingerss so that the latter act iii-conjunction.with a bridge pieee ll to retain the wili ifiTi instgthe under face of the hack saddle, or in thefcha n i el thereof. duct 12 extends through th'top face of theback saddle. and communicates with passage! so that lubricant-may befed to the wick from above the back saddle.

ll'a ring thus described my invention, what i I claim as new and desire to secure'by Let-- ters latent is 4 .l. in a top roll saddle, aback saddle havinf; a pair of spaced upwardly extending apertured lugs with slots 'leadinginto the a ertures, a pair of spaceddepending fingers on the hack saddle adapted to engage on Qpposite'sides of a roll, and a front saddle havin e a stem slidable in said apertures of the. lugs and having: a stop movable through the. slots and engageahle with the lugs t0.

prevent disenga 'ement of the. saddles except when the stop registers with the slots.

2. In a top roll saddle, a front saddle, a rear saddle, roll engaging means borne by the rear saddle whereby when in one osition the rear saddle will engage one rol and upon endwise reversal of the rear saddle' the latter will engage two rolls, and means to connect the saddles and to limit the longitudinal movement therebetween so as to require endwise reversal of the rear saddle when said saddle is to be changed from a one to a two r011 engagement and vice versa.

3. In a top roll saddle, a front and a rear e,

saddle, the rear saddle in one position being engageable with one roll and in an endwise reversed position being engageable with two rolls, and means to connect the saddles and to limit movement therebetween whereby to require endwise reversal of the rear saddle in changing same from a one to a two roll engagement and vice "ersa.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
